Paste a screenshot of what you see in the browser when you try to get to it, including the address bar of the browser.
Also tell us whether the browser is running on the same machine as node red.
If it is on a different machine then on the node-red machine, in a terminal, run
```auto
ifconfig
```
and paste the result here

Looking back at what you said earlier, you said that you had renamed the flow file to flow\_new and restarted node-red, but the log you posted shows it using that flow when it should have made a new empty one. Can you rename it again and restart node red. Don't do anything else. Then you should see it starting with a new empty flow.

Yes, something in there was causing a hangup and preventing it from fully starting. There should be a backup flow called
`.flows_H00something.json.backup` where you can see the name in the first log you posted, I can't easily read the screenshot. Note the dot on the front of the filename. If that is there then it should be the flow from before you made the last change. First make a copy of it under a different name so you can get it back if you want it, then rename it to whatever your current flow file name is and try that.

ok thanks for support.
I imported the old flow and Node-RED works fine 👍

The moral is to keep regular backups of your flow.

If you use the projects feature with a repository on another machine then that becomes very easy as each change you make is recorded and you can easily backtrack to previous versions.

What are you putting in the browser url?
Is node red running on the same machine as the browser or on a different machine?
Post here the log seen when starting node-red (from the Welcome to node-red message).

I am using Siemens IOT2040.
and i am using Putty to access it from my PC.
before nodered was working properly.
so the problem started when i changed the IP address of my IOT2040. and then when i am entering 192.168.200.1:1880 to my browser it can't reach nodered.
It is showing the error shown in picture.

You are trying to use Node-RED v0.20.5 with nodejs v6.12.3
as per the release notes for v0.20 it requires nodejs v8 as a minimum
> **[Version 0.20 released](https://nodered.org/blog/2019/03/12/version-0-20-released#nodejs-version-support)**
>
> Find out more on the blog
So normally I'd suggest upgrading to nodejs v8, but you will need to check what version of nodejs the Siemens IOT2040 supports. If the latest is nodejs v6 you will need to downgrade Node-RED to v0.19.x
So the problem must have started when you upgraded Node-RED rather than just changing the IP address

That surely depends on how you installed it.
If you installed using npm then there is an npm syntax to specify the version to install, which you can google. It's not something I've ever needed to do.
